Does tea and coffee count towards the recommended 8 glasses of water a day?

In a word, yes – other beverages do count towards your daily liquid consumption. Many people take the water advice a bit too literally and assume that, even if they are drinking other beverages, they still need to drink 8 glasses of plain water too.

We as humans are made up of approximately 60% water, so it’s important for healthy nails, skin and hair, it also helps up control our blood pressure, body temperature and heart rate. To help us stay hydrated we can drink water and any other fluids as well as hydrating foods.


This confusion came from the thought that caffeine is considered a diuretic, if caffeine makes you urinate, then a caffeinated drink will surely cause you to lose more water than you take in, so a caffeinated drink can’t really be a fluid – maybe it’s more like a ‘negative fluid’.


Doses of caffeine equivalent to the amount normally found in standard servings of tea, coffee and carbonated soft drinks appear to have no diuretic action”. So there you go; caffeinated beverages definitely “count” when it comes to meeting fluid needs.


Actually, all beverages can contribute to your fluid requirement – like coffee, tea, fruit juice, broth, vegetable juice, sports drinks and low fat milk – since they’re primarily water.


Most of us need around 3 litres of liquid a day, of course this depends how active you are, your age and your gender. Temperature does not matter in terms of hydration, warm, cool or cold will hydrate you. Fruit and vegetables provide around 20% of your water needs. In addition, a meal containing some broccoli, brown rice, salad and water melon for dessert contains almost 3 cups of water, as a comparison a cheeseburger and chips contains less than half a cup of fluid.


drinking water whilst eating does not dilute your digestive juices, or impair digestion in any way. As long as you drink over the course of the day it doesn’t matter when you consume it.


Bottled water is no safer than tap water, tap water standards are set by the Environmental Protection Agency; water is regularly tested, and consumers receive annual reports on water quality.

165 million cups a day of tea are consumed in the UK alone.
